Towards component orientation in embedded Web Service environments

Service-oriented architectures and systems designs are powerful concerning reusability of functional blocks and hiding implementation details from functional interfaces. But to compose a complete application, often central entities and engines are required for processing a specific sequence of service. In component-based designs the component itself is capable of describing both not only their offered services and interfaces but also dependencies on other services and interfaces to fulfill a complete task or application logic. This paper investigates on how to transfer and enhance exiting component-based approaches, already known from business applications, into the domain of embedded web services environments. Special focus is on the Devices Profile for Web Services (DPWS) technology which features service orientation also in device centric applications. This paper introduces a new approach to create applications, based on services provided by devices deployed with DPWS, in an abstract and dynamic way.
